ENGRAVlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 738,149, dated September 8, 1903.

Application filed February 11,1901. Serial No. 46,805- (No model.)

To (all who/)2 it may concern:

Be it known that 1, TBA R. BEAM, a citizen of the United States, and a resident of Elmira, in the county of Chemung and State of New York, have invented a new and Improved Engraving-Machine, of which the following is a full, clear, and exact description.

This invention relates to a machine for engraving from patterns; and it comprises a IO tracer having connection with a graver, so that by moving the tracer over a pattern or copy the graver will be made to work on the plate to reproduce the subject of the copy or pattern.

The invention consists in certain peculiar features of construction and arrangement by which this end is effectively attained.

v This specification is the specific description of one form of the invention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the views.

Figure 1 is a perspective view of the invention. Fig. 2 is a sectional elevation showing the means for tilting the engraving-tool to shade the lines produced thereby. Fig. 3 is a fragmentary elevation showing the means 0 for mounting the vise which carries the plate to be engraved. Fig. 4 is a section looking down from the line 4 4; of Fig. 1. Fig. 5 isa section showing the device for carrying the engraving-tool. Fig. 6 is a sectional eleva- 5 tion illustrating the arms for carrying the graver and the means for mounting said arms, and Figs 7 and 8 are views showing the different positions assumed by the graver under the action of the devices shown in Figs.

2 and 6.

a indicates the base of the apparatus, on which are mounted rigidly the two standards Z) and c. The standard I) carries a device I) for holding securely the pattern or copy 5 which the engraver is to follow. The standard 0 supports an adjustable arm 0', to which is attached adjustably a bracket 0 carrying a slotted plate 0 To this slotted plate is attached the vise (Z, which holds the work, this vise being adjustable on the slotted plate by means of a set-screw (1. By means of the construction shown the vise may be tilted so as to hold the plate at an inclination to the workman, thus enabling him readily to inspect the progress of the engraving. Supported on the standard b at a point just above the base a is a lever 8, this lever being fulcruined by the devices which support it on the standard and such devices constituting a gimbal-joint, as indicated at the point e in the drawings. The upper end of the lever e is curved horizontally and carries a tracer e which is adaptedto work over the pattern held by the table I). The table is set at an angle facing the operator and may, if desired, be curved or bent to facilitate the work. The tracer e is provided with a handle e for facilitating its manipulationJ Fulcrumed to the standard 0 by gimbaljoint devicesf is a leverf, which is connected to the lever e by a link g, arranged at the lower ends of the levers and universally attached to the lever c, as indicated, at the point g. The upper end of the lever f carries a rod h, which is provided with two downwardlyprojecting lugs h, pivoted to a gimbal-ring 77. mounted on the upper end of the leverf. A spring h3 is connected to the gimbal-ring to hold the same normally in the posit-ion shown. The rod h is rockable on the gimbalring and has attached thereto an arm 1', to the outer end of which is connected a rod 2', extending downward to a treadle 11 mounted on the base a. A look i is provided for holding the treadlo in fixed position, this look being pivotally mounted on the base and movable into and out of engagement with the treadle. The lower end of the rod t" is universally connected with the treadle, as shown in Fig. 2. o

The rod h carries fast a vertically-disposed sleeve 7c, in which is fitted to turn the graver k. This graver is provided with a V-point, (see Fig. 5,) and, as here shown, the graver is pointed at each end and is adapted tobe 5 revolubly carried in the sleeve 7t". Also the form of graver here illustrated has its working V-point turned or bent slightly sidewise, as best illustrated in Fig. 6; but this construction is not essential, nor does it affect the loo proper operation of the apparatus, as will hereinafter appear. Attached to the upper end of the graver is a hand-wheel k which is removably held in place byanut k threaded on a contractible boss formed on the wheel 70 and surrounding the graver. WVhen the nut 70 is tightened, the said boss of the wheel rigidly embraces the graver 7a to hold it. A thumb-knob k is attached to the wheel k to permit the manual operation thereof, and by means of this thumb-knob k the graver may be turned in the sleeve 70 around the longitudinal axis of the graver to any position necessary to facilitate the operation thereof. In operation the graver should be adjusted vertically in the sleeve 7c, so that when the graver-point faces straight away from the pivots connecting the lugs h with the gimbalring 7L2 the working point of the graver lies in alinement with said pivots, as shown in Fig. 1. Owing to the mechanism described, upon pressing down on the graver it may be moved vertically toward or from the work. By turning the graver around its longitudinal axis it may be moved out of the position shown in Fig. 6 and presented sidewise or edgewise to the work, as desired, so as to suit the peculiarities of the work or the judgment of the workman. WVhen the graver is in the position shown in Fig. 6, by rocking the arm it around the pivots of its lugs 7L (which actionis effected by means of the treadle t the graver may be rocked on its very point from side to side, thus presenting the apex'of its V-point to the work (see Fig. '7) or tilting the graver sidewise, so as to present one of the diagonal sides of said V-point to the work,

(see Fig. 8,) thus producing a fine line or a broad shade-line, as desired. When these latter operations are being performed,the graver should be turned to and held at the relative position shown in Figs. 6, 7, and 8-7 a, facing straight away from the pivots h-and therefore the sidewise bend of the point of the graver does not affect the operation described. This arrangement is very useful in working on curved and other uneven surfaces, when it will become necessary to adjust the graver with respect to the surface on which it works. In short, by means of the multiplicity of positions which the graver may be made to assume work of any character may be inscribed on surfaces of greatly-varying form. Owing to the capability of adjusting the graver with the point of its V-shaped edge in alinement with the pivot of the lugs h, very delicate work may be effected, enabling lines of any desired character to be engraved. The graver is pressed by hand upon the work and its various adjustments are efiected either manually or through the action of the treadle i If desired, a wire or the like may be passed between the part 9 and the table to support the former when the parts are being adjusted; also, a lock may be used to hold the tracer rigid with the lever 6 when adjusting the device.

A pan or like receptacle Z may be connected to the standard 0 bya bracket Z, as shown in Fig. 1.

' By adjusting the parts as shown in Fig. l and moving the tracer 6 over the copy held by the table I) the engraving-tool It will be caused to move, following the outlines of the copy, and this copy will therefore be impressed upon the work held in the vise 6?. By operating the treadle t the armh maybe rocked and the work shaded as desired. The arrangement of the parts capable of adjustment described enables me to fit the apparatus to engraving work of any nature desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
